question about upgraded stock rotors
I see quite a few ppl running stock sized rotors that have been cross drilled and/or slotted. This has always been a question that ive been meaning to ask...whats more important? Swept area or cooling capability? Obviously the best way to upgrade your breaks is to increase the swept area (bigger rotors/pads) to help the heat dissipation. Now the question is....on the stock sized rotors, is it beneficial to decrease the swept area in favor of better cooling? Also...how well do the vents/holes work if you dont have a good brake duct for cold air?

Unless you track your car, it won't really matter. As far as drilled verses slotted, drilled rotors have a history of cracking from good track usage.
If your car is only driven on the street, it won't matter which rotors you use (plain/drilled/slotted). If you track the car, then drilled shouldn't be an option.
With stock sized rotors, your brake pads are going to play a bigger role than what type of rotor you are using.

Oh i know all of ^that above 
, im just asking will decreasing the swept area on a stock rotor by getting one thats slotted/drilled help the fading? Or should you preserve the swept area because the slots/drilled holes wont help w/o some good ducting? Ive just always thought that the slots wont work wonders without a good ducting setup, so you'd want to preserve the swept area....

If you are experiencing fading (with stock rotors), what you need to do depends on what type of fade you experienced and what you are currently running:
1. If you press the pedal and it gets "mushy", that's your brake fluid.
2. If you press the pedal and it's still firm, but you aren't braking, that's your brake pads.
If you are already running "track quality" components for pads and fluid, then you'll either need ducting or a bigger brake kit.
